To all whom it may concern.-

Be it known that I, LOUIS BVSMYSER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-lVheels, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My present invention has relation more particularly to that class of car-wheels the bodies of which are made of plates of metal suitably united to the metallic hubs and tires.

The object of invention is to produce a simple, light, strong, and durable construction of car-wheel, and this obj ect I have accomplished by the novel features of invention hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

Figure 1 is a View in side elevation of a car-wheel embodying my invention. Fig. 2 is a View in vertical cross-section on line 2 2 of Fig. l. Fig. 3 is an end view of the hub, looking toward its flange. Fig. 4 is an end view of the spacing-block that encircles the hub. Fig. 5 is a View in cross-section on line 5 5 of Fig. l. Fig. 6 is a view in cross-section on line 6 6 of Fig. 1. Fig. 7 is a view in vertical transverse section through a modified construction of wheel. Figs. S, 9, 10, and 11 are views in vertical cross-section through wheels embodying features of my invention, the constructions being modified in certain particulars.

Referring more particularly to the construction illustrated upon the ii rst sheet of the drawings, A designates the tire, and B denotes the hub of the wheel. The body of the wheel consists of dished metal plates C and C', these plates being pressed into proper shape from comparatively thin sheets of steel and being arranged with respect to each other as shownthat is to say, with their centers separated at considerable distance where they are joined to the hub and with their outer edges brought approximately together where they are connected with the tire. The plates C C` are formed with the raised and depressedcorrugations c and c', as shown, the corrugations c extending awpproximately the radial length of the plates and converging about the hub-openings of the plates, while the depressed corrugations c are located in those portions of the plates between the outer ends of the corrugations c. The central portions of the plates C .and C are preferably formed with the inturned flanges c2, and between the inner portions of the plates is set the annular spaceblock D, that is preferablyin the shape of the letter H in cross-section. This annular spaceblock D has its outer portion d connected with its inner portion by the web d, and the outer portion d of the block is corrugated to correspond with the corrugations in the opposite par-ts of the plates C and C. So, also, the inner face of the block D is preferably recessed to receive the inturned flanges of the plates C and C. The hub B has one end furnished with a flange b, the inner face of which is preferably corrugated to correspond with the corrugations of the coincident parts of the metal plates C and C', and over the opposite end of the hub B fits the retaining-ring b', the inner face of which is also corrugated to correspond with the portions of the plates C and C', against which it bears. The retaining ring b is firmly clamped against the metal plate by means of the screw-threaded nut b2, that is preferably formed of polygonal contour, so that it can be readily operated in order to firmly bind the parts together. The outer edges of the body-plates C and C are riveted to an annular tread-plate E, the Web e of which sets between the edges of the plates, and preferably the edges of the body-plates are slightly flanged or flared outwardly to afford a better bearing with the annular tread-plate E. The outer face of the annular plate E bears against the inner face of the tire A, the annular plate being disposed in such relation to the tire that the web c of the plate shall come beneath that part of the tire-tread which normally bears upon the central portion of the rail, and is consequently subjected to the most constant and direct strain. As the tire A is formed of sheet metal and of as light weight as can be employed for such purpose, it is desirable to reinforce the tread of the tire, so as to enable it to better resist the strains to which all parts of the tread are sub- IOO violently off and onto the tracks.

j ected, and particularly is this reinforcing of the tire-tread desirable where the Wheel is used for hand-cars that are constantly lifted For this reason I prefer to form the annular plate E with a flange e', extending beneath the outer portion of the tread of the tire, thereby greatly increasing the strength of the tire-tread at all points. Another advantage of thus extending the plate Ebeneath substantially the entire tread of the tire is that the frictional contact between the broad outer face of this plate and the inner face of the tire when the plate has been forced into position within the tire will avoid the necessity of bolting the plate to the flange of the tire. The tire A is formed with the rail-flange a of a shape corresponding with the shape of the standardgage-railway-Wheel flange, and is formed, also, preferably with the inner flange a', that may be doubled inward and clamped against the flange e of the plate E; or this flange o. might extend at right angles to the tread of the wheel.

A wheel constructed in accordance with the above description will possess a very great degree of strength, since the arrangement of the body-plates C and C is such as to most effectively distribute the strain about the hub of the wheel. So, also, the corrugations of the plates are such as to effectively guard against any danger of the plates collapsing under strain, and the inturned edges of the plates, clamped as they are between the annular plate or block D and the hub, are securely held against possibility of withdrawal or displacement and afford a square bearing against the hub for the centers of the plates. The tread-plate E A serves not only to securely retain the outer edges of the body-plates C and C together and to the tire, but affords such a bearing beneath the tread of the tire as to distribute the strains or shocks from the tread of the Wheel to the body in most direct manner.

In the form of my invention illustrated in Fig. S of the drawings the tireAof the wheel and the body-plates C and C are of substantially the construction hereinbefore described, although the plates are not shown as corrugated in this form of my invention. So, also, the annular tread-plate E is the same as that hereinbefore described, and in like manneris united to the outer edges of the body-plates C and C. In this form of the invention, however, the hub B is shown as screw-threaded at both its ends and is formed with annular ribs b4 about its central portions. Against these raised ribs b4 bear the annular rings b5, Within the openings of which and between such rings and the hub B set the inturned flanges of the plates C and C. Against the central portions of the plates bear the retaining-rings B, which may be screw-threaded in correspondence with the ends of the hub, and preferably, also, screw-threaded nuts or washers B2 engage with the threaded ends of the hub and serve to firmly hold the rings B and b5 against the body-plates C and C and securely retain thev rings in position upon the hub.

In the embodiment of my invention illustrated in Fig. 9 the tire A is of the same construction as that illustrated in the preceding figures of the drawings, except that the interior flange a extends at right angles to the tread of the tire. In this form of the invention the body-plates C and C are of the same general construction as that hereinbefore described, except that the plate C is of slightly greater diameter than the plate C in order to enable theouter edge of this plate C to bear directly against the inner face of the tiretread. In this construction the tread-plate E extends only on one side of its inner web e; but the outwardly-flanged edge of the plate C serves to supplement the tread-plate in transmitting the strain from the tire to the body of the wheel. In this form of invention, as in the forms above described, the treadplate is extended to the outer edge of the tiretread and the advantages incident to such construction are attained. The hub B is formed with the annular ribs b4, and is provided with rings B and b5, corresponding to the rings illustrated in Fig. 8 of the drawings; butin this form of the invention the hub is not screw-threaded, and the :rings are heldin proper position with respect to the hub and the body-plates C and C by means of through-bolts F, that pass through the plates and the rings. Y

'lhe modified form of wheelshown in Fig. l

IO of the drawings has a tire A, corresponding with the tire hereinbefore described, and in this form the body-plates C and C correspond With the body-plates illustrated in Fig. 9 of the drawings. S0, also, the treadplate E extends to the extreme outer portion of the tread. In this gure of the drawings I have shown the tread-plate as formed with an inwardly extending flange e2 abutting against the flange a of the tire A and riveted thereto for greater security. In this lastdescribed wheel the hub B is shown as formed of cast metal, this hub `being cast about the inner portions of the body-plates C, so that a firm union of the plates and hub is secured.

In the form of the invention illustrated in Fig. ll of the drawings the hub B is shown as in the last-described figure. In this construction, however, the outer edges of the body-plates C and C are brought together in such manner that the outer edge of the plate C extends beyond and overlaps the outer edge of the plate C and bears against the inner face of the tire-tread. So, also, in .this form of the invention the outer portions of the wheel-body are joined by through-bolts K to the depending flange a of the tire by means of a channel-plate I-I, that extends from Ehe wheel-body to the depending flange of the ire.

In the form of Wheel illustrated in Fig. 7 of the drawings the body-plates C and C are the same as those illustrated in Figs. l and 2, and these body-plates are united to the hub B in the same manner. The tread-plate E (shown in this view of the drawings) does not extend the entire distance from the body to the outer edge of the tread, but is bolted to the bodyplates C and C and to the interior tiange a of the tire by through-bolts K. ln order to hold the wheel-body at proper distances with respect to the interior flange ci of the tire, a spacing-ring M is placed between the outer portion of the wheel-body and the interior flange a', so that when the parts are joined together, as illustrated in the drawings, the spacing-ring M will serve to hold the wheelbody in proper position with respect to the tire.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isw- 1. A car-wheel the body whereof is composed ot metal plates having inwardly-turned flanges about their hub portions and a space block or ring between which and the hub the flanges of said metal plates extend, and a hub and tire suitably connected to said plates, substantially as described.
